We’re not going to do it … We’re not going to do it … Ok, we are. Winter is coming.

Good morning. It appears increasingly likely the Houston region will see its first real Arctic blast early next week, with a reasonable possibility for a freeze in central parts of the city, and possibly upper 20s north and west of Houston. While we are far from locking in temperatures yet, this is something to bear in mind for this weekend if you have plants outside that need to be winterized.

Thursday

The first of two cold fronts is on the way to Houston, but this will be a bit of an odd duck. The front is going to move through today, likely pushing from the northwest to the coast roughly from noon to around 6pm. Instead of a line of showers and thunderstorms, we are more likely to see kind of a mass of light to moderate rain, which may congeal into heavier rain showers and thunderstorms south and southwest of Houston. Hard to say for sure, to be honest.

Bottom line—if you live north or east of Houston you may not see much rain at all, but if you live in Sugar Land you might get 1 to 2 inches. While we will see winds shift with the front, and some drier air, cooler temperatures are going to lag several hours behind. As a result, highs today should get into the upper 70s, and fall to around 50 by Friday morning.

Friday

Some light showers may linger into Friday in the wake of Thursday’s front. Even after they stop, however, clouds will remain, and this will be a cold and gray day. Highs are unlikely to get out of the low 50s. Friday nights lows should drop into the 40s, but how far will depend upon your distance from the coast.

Today may be the last 80-degree day of 2019. (No promises!)

Good morning. It has only been 2.5 weeks since Houston experienced its last 90-degree day of 2019. But since then we’ve transitioned rapidly from late-summer weather into fall and now we’re teetering on winter-like weather (be sure and check the forecast for next week below). Anyway, I write that to say that I think today may be one of the region’s last 80-degree days for awhile and perhaps even the last such day of this year. Although that is certainly no guarantee.

Wednesday

We’ll see some high clouds today, but for the most part we can probably expect mostly sunny skies throughout today. Given the sunshine, and flow of warm air, we can probably expect high temperatures to nudge up to around 80 degrees today, or a bit warmer for some inland areas. Lows tonight will generally fall into the 60s—how far will depend upon your distance from the coast.

Thursday

Clouds will build Wednesday night, and Thursday should be a mostly cloudy affair. Highs should generally get into the mid- to upper-70s ahead of the cold front. There is still some question when the front will push into Houston, but I’d guess it will reach northern and western parts of the metro area by late afternoon, and push off the coast by or before midnight—but don’t hold me to that timing. Another question is rainfall. If there’s any agreement in the models it’s that the better chances lie south of Interstate 10, and closer to the coast. I still think most of the region will see between 0.5 and 1.0 inch of rain on Thursday and Thursday night, with the isolated potential for 2.0 inches or more for some areas near the Gulf.

Houston this week: Warm, cool, then cold

Good morning. With the warmer overnight conditions, some fog has developed over the area, particularly across the western metro area in places such as Tomball and Katy. Aside from that, our weather will be pretty mellow until Thursday, after which a succession of cold fronts bring winter-like conditions to the region by early next week.

Tuesday

Today will be warm as Houston falls under the influence of Gulf of Mexico air, with highs reaching up to about 80 degrees despite mostly cloudy skies. Forecast models are hinting at some very slight, very scattered rain showers today, but for the most part we’ll just see clouds. Low temperatures on Tuesday night should fall into the low- to mid-60s as winds become more easterly.

Highs Tuesday will be fairly warm, especially to the southwest of Houston. (Pivotal Weather)

Wednesday

We’ll see partly sunny skies on Wednesday, with highs in the mid- to upper-70s. Rain chances are near zero.

Thursday

We’re still not entirely sure what Thursday is going to look like, but most of the day ahead of a cold front should be fairly warm, especially for central and southern parts of the metro area. High temperatures will likely push up to around 80 degrees despite mostly cloudy skies. Moderate rainfall ahead of, along with, and just after the front will be likely on Thursday during the afternoon, evening in most of Houston, and perhaps continuing after midnight for areas along the coast. Accumulations of 0.5 to 1.0 inch seem likely for most, with a few isolated areas perhaps seeing as much as 2 inches of rain. Temperatures and dewpoints will fall after the frontal passage, which should occur during the late evening for most of the city.

A mostly quiet fall-like week for Houston lies ahead

Well, I hope you enjoyed that weekend. Sunday, especially, offered a mix of cool, dry air, and sunshine that were just about perfect for fall. It was hard not to spend most of the day outside. The good news is that next weekend should have a similar mix of pleasant fall air and sunshine.

Monday

Clouds have returned this morning to most of the metro area, indicative of the region’s changing air flow. As a result we’ll see higher temperatures—mid-70s, mostly—and higher humidity throughout the day. Skies should remain partly to mostly cloudy. Low temperatures on Monday night will not cool down much, only falling into the mid-60s for most of the area.

Tuesday

After several colder nights, the combination of these warmer nighttime temperatures, moisture returning from the Gulf of Mexico, and light winds will probably lead to the development of some widespread fog on Tuesday morning. A weak front will move into Houston, and perhaps stall near the coast, on Tuesday. This is unlikely to have much of an effect, but may generate a low chance of showers, perhaps 10 or 20 percent around I-10 or points south. For the most part this should be a partly to mostly cloudy day, with highs in the 70s.

Wednesday

This should be a partly to mostly sunny day, with highs in the 70s.
